Özet (Çeviri)
The aim of this study was to determine if increasing feed sliver moisture content would improve spinability in rotor spinning without deteriorating yam properties. Yarns were produced at high rotor speed and low twist level Two different count rotor spun yarns (18's and 24's) were spun from 100% cotton sliver at two different feed sliver moisture contents, and at two different opening roller speeds. Results indicated that increasing moisture content reduced the number of ends down, but increased yarn unevenness, and the frequency of thin places, thick places, and neps. In addition, the yarn elongation and work-to-break results were worse at high moisture contents. Another important finding was that high opening roller speed tended to improve spinability by reducing the number of ends down. Yarn evenness and thin and thick place results were also better at the high opening roller speed in the case of fine yarn. Overall, the results suggest that feed slivers with high moisture content can provide better spinning performance in rotor spinning. In other words, high moisture content can increase the production rate of open:end rotors, thus, reducing the production cost of rotor spun yarns. However, a high moisture content also tends to deteriorate yarn evenness, the frequency of imperfections and yarn elongation results which is a disadvantage for the total economics of rotor spinning.
